How wide should a ramp be for a wheelchair?
The ramp must have a 1:12 slope ratio. This means that there must be a one-inch rise in the ramp for every corresponding 12 inches of the ramp. Minimum width of 36 inches, although this can be higher in certain states. The ramp cannot be longer the 30 feet without a rest platform, in order to prevent fatigue.
Can I use 2×6 for wheelchair ramp?

What is the architectural standard for a wheelchair ramp?
– ADA Standards Require a 1:12 ramp slope ratio which equals 4.8 degrees slope or one foot of wheelchair ramp for each inch of rise. For instance, a 30-inch rise requires a 30-foot handicap wheelchair ramp. – ADA Guidelines Require a Minimum 5′ x 5′ Flat, unobstructed area at the top and bottom of the ramp.
What kind of wood should I use for a ramp?
pressure treated wood
Like a deck, ramps made from pressure treated wood are sturdy and resilient when properly built and maintained.
What is the correct angle for a wheelchair ramp?
4.8 degree angle
Maximum slope for hand-propelled wheelchair ramps should be 1″ of rise to every 12″ of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5″ rise to 12″ length (7.1 degree angle; 12.5% grade). Minimum width should be 36″ (inside rails) – (48″ is ideal).
What kind of plywood do you use for a handicap ramp?
